The pineal gland secretes the hormone melatonin (N-acetyl-5-methoxy
tryptamine), which suppresses angiotensin II-induced human antigen R expression through the inhibition of NF-KB signaling.
Postmortem studies have reported a decrease in 5-hydroxy
tryptamine (5-HT)1A mRNA levels in the hippocampus and prefrontal cortex of patients with MDD (110).
According to Strassman's opinion (2001), DMT can be considered as the simplest of the
tryptamine psychedelics.
In their paper, Olson and colleagues tested psychedelics from the amphetamine,
tryptamine, and ergoline drug classes.
In this study, a new diamine N-[2-(1H-indol-3-yl)ethyl]-3,5-diaminobenzamide (IEDAB) was synthesized using
tryptamine as starting material and characterized by FT-IR, [sup.1]H-NMR, [sup.13]C-NMR, and mass spectroscopy.
As already mentioned, a number of studies have highlighted the capacity of AhR to respond to indolyl metabolites, including indoxyl-3-sulfate, 6-formylindolo[3,2b]carbazole, kyneurenine, kynurenic acid,
tryptamine, indole-3-acetate, and dietary indoles (indole-3-carbinol and 3,3'-diindolylmethane from the Cruciferous vegetables), thus positioning the AhR as a candidate indole receptor [11, 15, 43, 44].

An additional alkaloid, DMT, is a
tryptamine derivative similar to serotonin that is found in the leaves of P.
Bacterial metabolites (indole, indolic acid, and
tryptamine) and endogenes (serotonin, melatonin, and kynurine) influence the microbial metabolism, microbiota composition, and host immune system [9] (Figure 1).
Tramadol is a well-known powerful centrally acting analgesic medication with established pharmacological effects on opioid systems (mainly [mu]-opioid receptors agonism) and nonopioid systems (5-Hydroxy
Tryptamine and Noradrenaline reuptake inhibition) [1].
